tor ~ N war was burnt In undOing the very
Lp,yyv d~;lition practised at Aska, although
that dllutiom is just double what the san
,verhauseu firm guarantee me. 70 put the
matter in another way. AT NOnp0fest, II
we dilnted tue product OF my daily task OF
400 tons of canes to the same extent as Is
lone at Aska,gI should require a triple
effect of $500 square feet OF heatlng sur
face TO take out the water which l had put
in. If, on the other hand, l diluted only
to the extent of 80 per cent; l should re-
0uire a triple effect with q total heating
surface of $500 square feet to restore my
Juice to it's original density. While on the
question. of fuel [ may as well sum up all
Trhave to say or the matter. l have al
ready said six boilers are kept con-
afanfly fred aC 4Aska, and Il have given
Won "a description of their make. lThe COCal
fuel consumed in the ASka works apart from
the fOundry-tliat rs tOsayy for tire cOflcfe"
tor furnaces, the boilers and the dlstlliery
averages throughout the crop six tons OF
wood to ten tons ,Of canes. Six IONS OF
wood mean, l suppose, ABOUT two tons
of coal, and ten tons of canes mean Que
ton of sugar +; and that in % factory where
diluti0n Is carried to its extreme extent,
and no great desire is shown to save fuel
or make the most out of the sweets. LII
addition to this, the chips were dried anu
burned, about one half of them during diI-
fusion season and the other half after It's
close. / estimate the chips consumed dur
ing the diffusion season to be equal to ABOUT
25stOns of wood, not a very material Item
spread over 1000 tons of sugar. When the
iaice leaves the concretor trays standing,
say at IL Beautn6, it is taken into tho dou-
Bile efet, which evaporates as nearly as
possible; One-thirl of q gallon per square
foot per hour, and is brought there TO
a density of about % to IS Beaum6. IGls
then struck, 400 gallons at a time, INTO a
kind of eliminator, where it is brought 10
boiling point five and six times, muctI as
we used sometimes to deal with our juice
III the old-time clarifer days. The syrup
is then. left for about fifteen minutes, after
which all except the extreme bottom is run to
the syrup tank, whence it is drawn to the
vacuum pan in the usual way. The maSse-
cutie in boiled up to 800 Beaum6, ana
struck out into iron boxes. It is very good
in appearance, and has scarcely any mo.
lasses on it's surface. In from "a TO 40
hours it is dug out with shovelS, plugged,
and run through the centrifugals. Az
white sugar is desired, Z Of q gallon OF water
at least is used for each centrifugal,
and steam is turned OH whenever needed.
AS a result they obtain from Al to A per
cent. OF pure WnlI0 sugar Auo WVieeSS0'
is boiled up, and struck into the bamboo
lined boxes which I have described. In
the event of u specially dry molasses sugar
being required they sun their second pro,
duet for five or six hours on the roof OF
their factory before they bag it. AS arule
however, the sugar is simply taken from
the boxes aud sent into consumption. From
the sample on the table you will see that 1t
is decidedly superior TO the ordinary mo-
lasses sugar stripped from this colony. In
default ola good focal market they simply
store their sugar, and refine it as soon AS
theiroln no huiidfed days. diffusion season is
ever! 3Wheip refined it yields 40 per cent.
ofpurei white sugar, the molasses reboiled1
gives a further. 7Ior 8 per cent. and the re.
haaining 2487p cent. OF the, miassecuite is
sent b to the sdistilIery: /" Owing to these
various methods Of dealing with the second
sugar it was difacalt to get an absolutely
exact return of the second quality sugar re-
suieing from the canes. All through there
was perfectly plain sailing as far as the
NsaSsecuite was concerned. This masseeuite
weighed 93l lbs. to the cubic foot, and 10
TODD per cent. w8, obtained from the
canes, the juice averaging 81 B. This L
take to- be fully 20 TO Is per cent. more
than we get In this colony from similar
caneso Before I.leaYe this part of the sub
